Could not install packages due to an EnvironmentError: [Errno 13]

Question

In my MacOS Mojave terminal I wanted to install a python package with pip. At the end it says:

You are using pip version 10.0.1, however version 18.1 is avai         


        

Answer 1

On Mac, there is no 3.7 directory or the directory 3.7 is owned by root. So, I removed that directory, create a new directory by current user, and move it there. Then installation finishes without error.

sudo rm -rf /Library/Python/3.7
mkdir 3.7
sudo mv 3.7 /Library/Python
ll /Library/Python/
pip3 install numpy
